Plugins Not Installing / Updating

Hi,

I’m suddenly getting the error “could not create directory” when I try to install a new plugin or update an existing plugin on one of my sites.

This happened on the dev site and was fixed after upgrading to 4.2.2. On the live site, I’m still getting the same error, though. I’m running the same plugins (and versions) on both sites, in fact there are a few more on the dev site since I’m periodically testing new things. The only substantive difference between the two sites is that one is a dev and therefore not public. They’re both hosted by the same company and both running an older version of Avada theme.

This is the site https://www.devonhouseseniorliving.com.

Any suggestions on how to track down the issue would be greatly appreciated.

Thanks!
